As an important safety component in new energy vehicles, high-voltage customized Electric vehicle DC contactor from China should have the characteristics of shock resistance. The main reasons are as follows.
Because the customized electric vehicle DC contactor for new energy vehicles must not only have the basic elements to withstand higher working voltage and carry sufficient current. The customized electric vehicle DC contactor from China should also be able to resist the impact of the large amount of current of the capacitor load at the moment of closing. The amount of current that the customized electric vehicle DC contactor has to bear is generally many times to dozens of times the rated voltage of the load.
The basic customized Electric vehicle DC contactor from China cannot bear the impact of this instantaneous current, and the damage of this impact current is very easy to cause the contact of the contactor to stick. However, the contacts of the customized Electric vehicle DC contactor are ineffective when separated, and the switching power supply cannot be controlled without being disconnected. Therefore, the customized Electric vehicle DC contactor from China for new energy vehicles should have excellent impact resistance characteristics.
